Description

Technical Field

[0001] This utility model relates to the field of mobile power bank technology, specifically a mobile power bank with a stand. Background Technology

[0002] A power bank, also known as a portable charger or power bank, is a portable charging device that can be carried around. It is mainly used to charge handheld mobile devices such as mobile phones, tablets, and headphones. Power banks store electrical energy through their built-in batteries, and when they need to charge other devices, they transfer the stored electrical energy to the target device through output ports such as USB interfaces.

[0003] Application number CN221828621U discloses a portable power bank, relating to the field of portable power bank technology. The power bank includes a charger with at least one portable power bank magnetically attached to its top. Both the charger and the portable power bank contain magnets that attract each other. The charger's output port and the portable power bank's input port are in contact. The portable power bank has a magnetic wireless charging function inside, and a charging cable is also provided on one side. The magnets are either circular or elongated. Both the charger and the portable power bank contain at least two magnets. Both are flat. The charger automatically charges the portable power bank. The magnetic attraction between the top and bottom magnets allows for easy assembly and disassembly, achieving portability, compact size, and lightweight operation. The structure is simple and compact, economical, and has broad application prospects.

[0004] Existing technologies utilize components such as magnets, output ports, and chargers to achieve the function of energy storage. Energy is input and stored through the output port of the charger and the input port of the power bank. The power bank is automatically charged by magnetic attraction between the upper and lower magnets. However, during the process of inputting power into the power bank, the internal components are prone to generating heat, which can damage the internal components if the high temperature is maintained for a long time. In addition, when charging mobile phones and other devices, the power bank and the charging device need to be placed stably and fixed, which makes it inconvenient to use the charging device during the charging process, thus limiting the use of the power bank.
